The first German coin of 5 euros using the polymer was minted last year, 2017, and is dedicated to the Tropical Zone. The tropical climate is usual in the Tropics, in a band that surrounds the equator from 23º north latitude to 23º south latitude. This climate is due to the perpendicular angle of incidence of solar radiation that occurs in these regions during all year, which causes the temperature to be high.

The design of the coin is made by the artist Stefanie Radtke, he focuses on the biodiversity characteristics of the Tropics. This diversity is represented by a parrot flying over some trees. The red ring defines the transition to an open space where other birds are shown farther away and the words, in German, "TROPISCHE ZONA" (Tropical Zone) appears.

The second coin of the Climate Zones series is dedicated to the Subtropical Zone. The subtropical climate is the one that predominates next to the Tropical Circles. Simplifying, the subtropical regions are those where the average annual temperature does not fall below 18 ° C, and in Winter, the average is between 18º C and 6º C.

About the design, the reverse corresponds to the artist Patrick Niesel. He tries to represent a winter image of the humid subtropical zones with Mediterranean climate. For this, he represents the typical flora and fauna of this climatic zone: the domestic goats on the bushes, an umbrella-shaped tree that abounds in that area, and the sea at the bottom, represented by a straight line on the horizon.

All coins in this series have the same heads and also the same plain edge with the inscription in German: "KLIMAZONEN DER ERDE" (climatic zones of the earth).

The tails has been designed by the artist Stefanie Radtke, and it shows an eagle, symbol of Germany, together with the inscription "BUNDESREPUBLIK DEUTSCHLAND" (Federal Republic of Germany). The face value of "5 Euro" also appears, as well as the year of minting and, and depending on the mint house, the mint mark "A" (Berlin), "D" (Munich), "F" (Stuttgart), "G" (Karlsruhe) or "J" (Hamburg). In addition, each of the five German mints will give a different tone to the color corresponding to each year.

These coins are minted in copper-nickel alloy having a ring of translucent polymer in the center. The coin appears in two different finishes: BU (3 million units) and Proof (400k units). It should be noted that the coins in BU finish can be acquired in the banks of Germany at their face value, this fact has contributed to increase the interest in them at the same time that they can suppose a help regarding to funding our collections.

In addition to the series dedicated to the Climatic Zones, and due to the enormous interest that they have raised among the collectors, Germany has decided to mint another series of coins with this same plastic polymer called "Air in movement".

These coins will be minted in a nickel-copper alloy and they will also contain a translucent polymer ring. Unlike the previous ones, these coins will have a face value of 10 Euros and the Series will consist of only three coins, which will be put into circulation throughout 2019, 2020 and 2021.

The heads of the coin, designed by Natalie Tekampe, represents the image of a person flying in a paraglider between two mountains, and at the top of the coin you can read "IN DER LUFT" (IN THE AIR).

The tails designed by Andre Witting, will be common to the entire series, and has a similar design to the previous ones. In the center a stylized eagle and the face value "10 EURO" are represented together with the inscription "BUNDESREPUBLIK DEUTSCHLAND" (FEDERAL REPUBLIC OF GERMANY). In addition, it will be completed with the year of minting of each minting house and its mint mark: "A" (Berlin), "D" (Munich), "F" (Stuttgart), "G" (Karlsruhe) or "J" (Hamburg).
